Embodiment 1

[0025] A method for preventing and treating diseases of japonica rice, comprising the following steps:

[0026] (1) 7 days before the breach of the japonica rice, use tebuconazole solution, the mass fraction of the tebuconazole solution is 5%, and the application rate is 85mL / mu;

[0027] (2) 3 days before the breach of the japonica rice, apply the first mixed pesticide of trifloxystrobin, propiconazole and difenoconazole, the mass fraction of the first mixed pesticide is 5%, and the trifloxystrobin The mass ratio of ester, propiconazole and difenoconazole is 3:2:2, and the application rate is 45mL / mu;

[0028] (3) 15 days after the full ear of the japonica rice, apply the second mixed pesticide of Jinggangmycin and brassinolide, the mass fraction of the second mixed pesticide is 10%, and the Jinggangmycin and brassinolide The mass ratio of steroid lactone is 5:1, and the application rate is 30mL / mu.

[0029] The advantage of the invention is that multiple pesticides are use...

[0041] (2) 3 days before the breach of the japonica rice, apply the first mixed pesticide of trifloxystrobin, propiconazole and difenoconazole, the mass fraction of the first mixed pesticide is 8%, and the trifloxystrobin The mass ratio of ester, propiconazole and difenoconazole is 3:2:5, and the application rate is 45mL / mu;

[0042] (3) 15 days after the full ear of the japonica rice, apply the second mixed pesticide of Jinggangmycin and brassinolide, the mass fraction of the second mixed pesticide is 15%, and the Jinggangmycin and brassica The mass ratio of stenolide is 5:3, and the application ra...

Embodiment 3

[0044] This embodiment is basically the same as Embodiment 1, except for the following content.

[0045] A method for preventing and treating diseases of japonica rice, comprising the following steps:

[0046] (1) 7 days before the breach of the japonica rice, use tebuconazole solution, the mass fraction of the tebuconazole solution is 8%, and the application rate is 85mL / mu;

[0047] (2) 3 days before the breach of the japonica rice, apply the first mixed pesticide of trifloxystrobin, propiconazole and difenoconazole, the mass fraction of the first mixed pesticide is 8%, and the trifloxystrobin The mass ratio of ester, propiconazole and difenoconazole is 3:2:3, and the application rate is 45mL / mu;

[0048] (3) 15 days after the full ear of the japonica rice, apply the second mixed pesticide of Jinggangmycin and brassinolide, the mass fraction of the second mixed pesticide is 12%, and the Jinggangmycin and brassica The mass ratio of steroid lactone is 5:1, and the applicatio...

Abstract

The invention discloses a japonica rice disease prevention and treatment method, which comprises the following steps: (1) applying a tebuconazole solution 7-10 days before the japonica rice is brokenwith the application amount being 80-90 mL/Mu; (2) applying a first mixed pesticide of trifloxystrobin, propiconazole and difenoconazole 2-3 days before the japonica rice is broken with the application amount being 30-60mL/Mu; (3) 15 days after full heading of the japonica rice, applying a second mixed pesticide of validamycin and brassinolide with the application amount being 10-50 mL/Mu. According to the invention, multiple pesticides are combined for use, and brassinolide is added into validamycin as an additive, so that the method not only can prevent and treat ustilaginoidea virens, but also can prevent and treat other diseases.

Description

technical field [0001] The invention relates to the technical field of rice field disease prevention and control, in particular to a method for preventing and treating japonica rice diseases. Background technique [0002] During the growth process of japonica rice, diseases will appear, such as rice smut, sheath blight and rice blast, and some will also have black-streaked dwarf disease, which must be controlled for japonica rice. [0003] Among the diseases of japonica rice, rice smut has the highest probability of occurrence. In actual production, it is necessary to focus on the control of rice smut and pay attention to other diseases. In the prevention and control, one of Jinggangmycin, Aimiao, hexaconazole and tebuconazole is generally selected, and applied before the breach and after the earing, respectively. [0004] Existing japonica rice disease control mostly uses a single pesticide, and the control effect is relatively poor, especially for the control of diseases ...
